Abstract

The invention relates to the technical field of printed steel sheets, in particular to a printed steel sheet and a preparation method thereof. The printed steel sheet includes a hot-dip galvanized steel sheet layer, a primer layer, a transfer ink layer, an adhesive layer and a topcoat layer bonded in sequence, The materials for the topcoat layer include the following raw materials by weight: 20-30 parts of polyvinylidene fluoride, 0.2-0.6 parts of polyamide wax, 0.003-0.03 parts of fluorocarbon surfactant, 0.2-0.8 parts of carbon nanotubes, Solvent A50-60 parts. The printed steel plate of the present invention not only improves the lubricity of the topcoat layer, reduces the surface friction coefficient, but also improves the hydrophobicity of the topcoat layer, and is more conducive to allowing rainwater to wash away the dust on its surface in an open-air environment, improving self-cleaning performance, Avoid the dewdrops that condense more easily due to dust accumulation on the surface of the printed steel plate due to the temperature difference between day and night to accelerate the corrosion of the printed steel plate, thereby improving the environmental corrosion resistance of the printed steel plate.

Description

technical field [0001] The invention relates to the technical field of printed steel plates, in particular to a printed steel plate and a preparation method thereof. Background technique [0002] Printed steel plate, also known as printed color steel plate, refers to a steel plate printed with various patterns or patterns. It has the characteristics of light weight, beautiful appearance, and strong decoration. Printed steel plate can be used in home appliances, furniture, doors and windows, signs, outdoor decoration, etc. . Although the printed steel plates in the prior art have relatively rich colors, they are still poor in wear resistance and environmental corrosion resistance when used in outdoor environments. Contents of the invention [0003] In order to overcome the disadvantages and deficiencies in the prior art, the object of the present invention is to provide a printed steel plate with wear resistance and environmental corrosion resistance. [0004] Another obj...
